A nurse is assisting with the care of a client who is postoperative and has a closed-wound drainage system in place. Which of the following actions should the nurse take?

A. Irrigating the tubing of a closed-wound drainage system is not recommended, as it can introduce pathogens and compromise the sterile system. Proper care involves monitoring and emptying the drainage, not routine irrigation. B. After emptying a closed-wound drainage system (such as a Jackson-Pratt or Hemovac), the nurse should fully compress or recollapse the reservoir before reconnecting it. This restores the suction needed to continue effective drainage and prevent fluid accumulation at the surgical site. C. The drainage plug should be replaced before releasing hand pressure, not after, to maintain a closed system and avoid loss of suction. Releasing pressure before replacing the plug can allow air to enter and reduce drainage efficiency. D. The reservoir should be emptied more frequently than once per day, typically every 4–8 hours or when it is about half full, to prevent backflow, leakage, or impaired suction. Waiting an entire day can lead to fluid accumulation and increase infection risk.
